Description:Kenyan armed forces are going door-to-door in a hunt to find those responsible for a second day of killings. They're going after Somali-linked Islamist militants who killed at least 15 people on Kenya's coast on Monday evening. This, less than 24 hours after an earlier assault on a nearby town left almost 50 dead. One commandant says they're working tirelessly to find those behind the attacks.(0:50)
